Sleep++ uses your Apple Watch to track your sleep

David Smith, the developer behind apps such as Feed Wrangler, Pod Wrangler, and Pedometer++, has released a new app that uses the Apple Watch to track your sleep. Sleep++ uses the motion tracking capabilities of the watch to measure both the duration and quality of your sleep.

To use the app, you'll need to wear you Apple Watch while you sleep. You open the watch app and tap the Start Sleeping button, then tap Stop Sleeping when you wake up. But for those of you who might wonder when to charge your watch if you wear it while you sleep, Smith has an answer:

The TL/DR is to charge your Apple Watch in the morning while you get ready for your day (take a shower, get dressed, etc) and then again in the evening while you get ready for bed (brush teeth, put on pajamas, etc). Then put your Apple Watch in Airplane Mode while you sleep.

While Sleep++ is focused on the Apple Watch, you can use the iPhone app to view your sleep data as well. Additionally, the app utilizes HealthKit, letting you save data to the iPhone's Health app if you wish. Sleep++ is free to download, and an in-app purchase of $1.99 will remove ads from the app.
